1. Distribute the negative (in reality a -1) to everything inside the
parenthesis
- %2810y%5E3-6y%5E2%2B2y%29-%285y%5E3-2y%5E2-y%29
- 10y%5E3-6y%5E2%2B2y+-5y%5E3+-%28-2y%5E2%29+-%28-y%29
2. Then combine like terms
- 10y%5E3-6y%5E2%2B2y-5y%5E3%2B2y%5E2%2By
- %2810y%5E3-5y%5E3%29%2B%28-6y%5E2%2B2y%5E2%29%2B%282y%2By%29
= 5y%5E3-4y%5E2%2B3y
